产品特点Product characteristics

1、泵结构紧凑，机泵一体化，体积小。其立式结构具有安装占地面积小，运行平稳，安装无需调整。
2、泵进出口设计成规格相同法兰，且位于同一中心线上，可象阀门一样直接安装在管路上，且中心低，便于管道布置，安装特别方便。
3、泵与电机同轴，轴向尺寸短，使泵运行更加平稳，噪音低。
4、取消传统轴封方式，避免了输送介质的外泄，因此具有完全无泄漏的显著特点。
5、用滑动轴承替代常规电机滚动轴承，使泵具有运行特别平稳，振动噪音极低。
6、安装检修方便，无需拆动管路系统，只要拆下连接体螺母即可抽出全部件进行检查和维修。
7、可根据使用要求即流量和扬程的需要进行泵的串、并联运行方式。
1. Compact structure, integrated motor and pump and small volume. Vertical structure contributes to small occupation space for installation, smooth operation, and installation with no need of adjustment.
2. Pump inlet and outlet are designed with flanges of the same specifications, and also located on the same centerline. It can be directly mounted in pipeline, just as if a valve. For its low center, it makes pipeline arrangement and installation fairly easy.
3. Pump and motor share a common shaft for short axial dimensions, making it working more smoothly and little noise.
4. It has dispensed with the conventional shaft seal to avoid leakage of medium, so, it is completely leak-tight.
5. Sliding bearing instead of the conventional rolling bearing, making pump working more smoothly with very little vibration and noise.
6. Easy installation and maintenance, with no need to open pipeline system, only need to take off the connecting nut, and then all parts can be taken out for examination and maintenance.
7. Series or parallel operation according to the requirements of flow and head.
